An event generator for decays at NLO in SMEFT matched to a parton shower
Livia E. G. Maskos, Benjamin D. Pecjak, Shakeel Ur Rahaman +1
We present a Sherpa implementation of NLO corrections in dimension-six Standard Model Effective Field Theory (SMEFT) to the benchmark process . The calculation includ…
Feasibility of ultrarelativistic bubbles in SMEFT
Upalaparna Banerjee, Sabyasachi Chakraborty, Suraj Prakash +1
A first order electroweak phase transition probes physics beyond the Standard Model on multiple frontiers and therefore is of immense interest for theoretical exploration. We condu…
One-loop Effective Action up to Dimension Eight: Integrating out Heavy Fermion(s)
Joydeep Chakrabortty, Shakeel Ur Rahaman, Kaanapuli Ramkumar
We present the universal one-loop effective action up to dimension eight after integrating out heavy fermion(s) using the Heat-Kernel method. We have discussed how the Dirac operat…
EFT, decoupling, Higgs boson mixing, and higher dimensional operators
Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +3
The effective field theory (EFT) framework is a precise approximation procedure when the inherent assumptions of a large-scale separation between the Standard Model (SM) and new in…
Integrating out heavy scalars with modified EOMs: matching computation of dimension-eight SMEFT coefficients
Upalaparna Banerjee, Joydeep Chakrabortty, Christoph Englert +2
The shift in focus towards searches for physics beyond the Standard Model (SM) employing model-independent Effective Field Theory (EFT) methods necessitates a rigorous approach to…
Memories of quenches in operator mixing
Joydeep Chakrabortty, Diptarka Das, Bidyut Dey +2
We work perturbatively with an interacting quantum field theory comprised of two distinct scalar fields. In this theory, we introduce a sudden quench of the mass of one of the scal…
EFT Diagrammatica II: Tracing the UV origin of bosonic D6 CPV and D8 SMEFT operators
Wrishik Naskar, Suraj Prakash, Shakeel Ur Rahaman
In recent times, SMEFT, along with a superlative repertoire of theoretical and computational tools, has emerged as an efficacious platform to test the viability of proposed BSM sce…
